biological: use full disrupt to take away 100 focus so he restore it and take damage. crystallize is also important to stun him and heal (so it not a sure-kill from tick-tock)do not use crystalize while he has deep burning or holy scars
psychological:use full haunt and wraith form is also recomended to use multiple focus-draining attacks per turn salvation and free will are useful here, too both should be used on veradux so he can heal you and roald (roald can take hits for you and distract the enemy)
Hydraulic:use regulate, and guardian form is useful too so veradux can heal more on roald who can distract the enemy
do not let him use eletrical storm cause he will regen focus. when he gets holy scars set veradux on relentless and kill BARON
Easy. just restock all your attributes, make your strength really high, and get predator form. Once you have that, it will be incredibaly easy to defeat him

For cold hydros, you will have to go on the defensive. This is done by putting four points each on mind freeze and flash freeze. At the start of each battle, use either mind freeze or flash freeze. When the effect wears off (unless if Roald's shell shock or slience is present on the Baron), continue using mind freeze or flash freeze. Repeat until the Baron has only half his hp (around that) or when he gets hit by holy scars. I found this out after combat against the Baron show that he only can use electric storm and no other attacks including tick-tock and after he uses it, he has to skip for one turn.
